3. Physical environment and Obstructions
Open areas provide better coverage range than closed areas. Also, the
obstructer such as steel buildings or trees can block or decrease communication
between bridges. To avoid this situation, the antennas should be located in where
is no or few obstruction between the sending and receiving antennas.
4. Rooftop Installation
Rooftop installations offer several advantages such as Fewer obs tacles in
path, Increasing the range of antenna, reducing multipath problems and
Improving performance due to greater height. But please notice that Rooftop
Installations are extremely dangerous! Incorrect installation way may cause in
serious injury or death. Such installations should be performed by the professional
installer.
5. Throughput of Data
Coverage range is inversely proportional to data rates. The maximum radio
range is achieved at the lowest workable data throughput .
